Lithification is the process by which sediments combine to form sedimentary rocks. ... The ions get deposited in the spaces and then crystallize, forming new minerals that grow and glue the unconsolidated grains together into rock.

How does lithification contribute to the creation of sedimentary rocks?

Sedimentary rocks are made of fragments of older rocks or pieces of organisms. Compaction and cementation lead to lithification of sedimentary rocks. ... Cementation is when cement from fluids bind sediments together.

What rocks form from the lithification of sediments?

These rocks are often called clastic sedimentary rocks. One of the best-known clastic sedimentary rocks is sandstone. Sandstone is formed from layers of sandy sediment that is compacted and lithified. Chemical sedimentary rocks can be found in many places, from the ocean to deserts to caves.
